This paper is concerned with the structural damage detection of three stories frame models by free vibration equation, in combination with the filtering theory. The structural damage analysis is formulated as an inverse problem. The formulated inverse problem is analyzed under the consideration of stochastic properties on the response of structural system. In this study, filtering algorithm based on projection filter is employed as the analytical methods of inverse problem. First of all, the characteristic of filtering algorithm based on projection filter is discussed by numerical simulation, and the data obtained by the experimental modal analysis are employed in numerical performance as the observation data and noise based on the consideration of stochastic properties.
